CONSTRUCTION OF FIREPROOF BUILDINGS.

Application filed May 18,

My invention, herein, consists of a novel and simple device, .by which Iapply the principle of the wedge to stretch and interlock thereinforcements with the supports of the infilled structure, and while myinvention may be utilized in arious ways, I have described it applied tofireproof floors.

In the accompanying drawings, where similar numerals indicate similarparts;

1 illustrates my invention before the wedgi 1g of the reinforcement,against the support of the infilled structure, has taken place.

Fig. 2 illustrates my invention after the wedging of the reinforcement,against the said support, is done.

Fig. 3 is a plan view of my invention showing the reinforcements inplace, and ready to receive the infilling.

Numerals 1 designate the reinforcements. Numerals 2 designate hookswhich hold reinforcements 1 to beams 3. Beams 3 support the floor, andnumerals 4c are columns which, in turn, support beams 3. Numerals 5designate wedgeshaped elongations attached to reinforcements 1. Numeral6 designates the place, on beam 3, against which the wedgeshapedelongation 5 is driven. Numeral 7 is the end of the wedgeshapedelongation 5.

Reinforcements 1 may be of any suitable design; I attach, at the one endof reinforcements 1, hooks 2, which hold reinforcements l firmly tobeams 3. Between beams 3, and under reinforcen'ients 1, I place ahorizontal form (not shown) upon which the fireproof infilling is laid.The fireproof infilling, together with the reinforcements 1, forms thefloor, and beams 3 serve as supports for this floor, while columns a, inturn, support beams After having described the above I am now coming tothat which constitutes my invention, herein.

In order to stretch and interlock reinforcements 1 with beams 3, I addthe wedgeshaped elongations 5, to reinforcements 1, at the opposite endsto hooks 2.

In Fig. 1 I have shown that the length of reinforcement 1 just allowsend 7, of the wedgeshaped elongation 5, to clear beam 3 at 6. Due to thefact that the angle, between wedgeshaped elongation 5 and rein- 1926.Serial No. 109,891.

forcement 1, is not less than 90, and that hook 2 is firm with theopposite beam 3, the wedgeshaped elongation 5 will, when driven, bewedged against 6, and consequently stretch and interlock reinforcement 1with. beams 3. If said angle had been less than 90, reinforcement 1would have dropped loosely on beam 3, after the end 7, of thewedgeshaped elongation 5, had passed 6.

Fig. 2 shows reinforcement 1, stretched and interlocked with beams 3,after the wedgeshaped elongation 5 is driven, and 5i 3 gives a plan viewof the reinforcements 1, in place, and ready to receive the infilling.When member 5 is driven the point 7 of 5 is llgi-enlti in, therebypreventing 5 from slipping I make reinforcement 1 a suitable fractionshorter than the distance between 6 and the point where hook 2 contactsbeam 3. Reinforcement 1 may, thereby, be stretched the length of saidfraction, when elongation 5 is driven against 6 of beam 3.

The simplicity of my invention facilitates a great saving in labor, aswell as a saving in wedgeshaped material.

Other modifications of construction may be made without departing fromthe spirit of my invention.

I claim 1. In a reinforcement of an infilled structure spanning spacedflanged beams, the combination of means for attaching the one end ofsaid reinforcement to a portion of one of said beams and the other endof said reinforcement bent to form a wedge-like member to engage theflange on the opposed beam, whereby said reinforcement is initiallytensioned and wedged to said beams when said member is driven.

2. In av reinforcement of an iniilled structure spanning spaced flangedbeams, the combination of a hook at one end of said reinforcementengaging the flange of the one of said beams, and the other end of saidreinforcement bent to form a wedge-like member to engage the flange ofthe opposed beam, whereby said reinforcement is initially tensioned andwedged to said beams when said member is driven.
